Ultra-Low Flow Metering of Wastewater
Ultra-Low Flow Metering of Wastewater
(OP)
thread161-357912: Low flow through 4" flume
I have an acid neutralization wastewater application where the city is requiring metering of the wastewater discharge prior to entering the city sewer. The amount of wastewater is about 200 gallons per day. This appears to be well below the minimum of all open channel flumes. I am considering using a batch system utilizing a pump and paddle wheel meter (or magnetic meter). Does anyone have any other ideas or recommendations?

The city may want an approved type or metrology tested unit if the unit is used for billing or compliance purposes. That may limit your choice.

I have a preliminary design showing a typical meter.

That should work well. Without having all the details though it looks okay, but you should double check that the flow meter meets the city's standards.

Your concept looks fine, but you should have a separate vault for the valves and flow meter.
